<div id="readability-page-1"><div>MONTREAL, May 13, 2026 /CNW/ - AtkinsRéalis Group Inc. (), a world-class engineering services and nuclear company with offices around the world, announced today it has signed a Strategic Alliance Agreement with First American Nuclear (FANCO) whereby AtkinsRéalis will act as the exclusive engineering, procurement, and construction management (EPCM) provider for EAGL‑1 small modular reactor (SMR) projects in North America. Work has already begun on the task orders, and the agreement contemplates services worth up to $250 million over the first five years.&#34;SMR technology is an important part of the energy mix needed to create stable, affordable, and reliable power grids that meet the energy needs of economies and communities worldwide,&#34; said Ian L. Edwards, President and Chief Executive Officer, AtkinsRéalis. &#34;This partnership with FANCO marks an important step in delivering innovative and scalable nuclear technology precisely when the United States is embracing a new era of energy leadership. As the government modernizes pathways for commercial reactor deployment, we are poised to help shape a safer, more secure energy future for generations to come.&#34;Under the first task orders, AtkinsRéalis will prepare procedures and policies required to do design work, such as a quality program and engineering procedures. It will also undertake the conceptual design for the balance of plant and review the design of the nuclear steam supply system. EAGL-1 is the only U.S. nuclear reactor design cooled by lead-bismuth, a liquid metal alloy that has been used in successful nuclear systems abroad for decades. The unique properties of lead-bismuth enable a simpler, more compact reactor design with fewer components and reduced complexity.&#34;The surge in US power demand is expected to intensify, largely by data centers and AI, as well as the need for greater grid resilience,&#34; said Joe St. Julian, President, Nuclear, AtkinsRéalis. &#34;We'll need all sources of efficient baseload power to meet the country's energy requirements, including large and small nuclear reactor technology, and we'll draw on our deep expertise working on SMR technologies around the world to deliver best-in-class services in support of FANCO's ambition to deploy a cost‑effective utility‑scale power across the US.&#34;AtkinsRéalis has a strong track record in providing engineering services for SMRs. It has served as the architect-engineer on Ontario's Darlington New Nuclear Project (DNNP) alliance team since 2023. The Company is working alongside GE Vernova Hitachi Nuclear Energy and Aecon Kiewit Nuclear Partners. DNNP is the G7's first grid-scale SMR and Canada's first nuclear new build in roughly 30 years. Since 2018, it has also supported the Rolls‑Royce SMR program in the UK with design and engineering expertise, as well as acting as the Owner's Engineer for Energy Northwest's SMR project in Washington state since 2024.About AtkinsRéalisCreated by the integration of long-standing organizations dating back to 1911, AtkinsRéalis is a world-class engineering services and nuclear company dedicated to engineering a better future for our planet and its people.
